Application led April 3, 1925. Serial No. 20,420.

This invention relates to a lubricating device for rolling mill rolls and the like, and has for one of its objects the provision of means for causing a consta-nt supply of lubricant under pressure to the surface to' be lubricated.

'Another object is to provide a device of this class which will hold or force grease against the surface to be lubricated under a. constant pressure.

A further, object is to provide a lubricating device having the novel construction,

design and combination of parts described.

in detail in the following specification, and illustrated in the accompanying drawings.

In the drawings:

Fi ure 1 is an end elevation of a stand of'ro s having my invention applied thereto.

Figure 2 is a plan of the lubricating device.

Figure' 3 isa sectional elevation taken on the line 'III-III of Figure 2.

Referring more particularly to the drawings, the numeral 2 designates a roll stand housing of well known and standard design having the usual opening or window 3 in which are mounted the bearing blocks 4 for supporting the necks 5 of the rolling mill rolls.

The resent invention is adapted to be mounted in the, window 3 of the housing and comprises a grease retaining box 6 adapted to be supported as shown on the lower bearing block 4 for each of the' rolls. The box 6 is composed of a bottom wall 7, end walls 8 and rear wall 9 are rigidly connected together. The end walls 8 have their forward free edges cut away as at l0 in a curve corresponding to the curvature ofthe roll necks 5 so as to snugly lit against said necks. box from front to back is such that it will have a relatively close fit between the side.

. one specific embodiment of my inventlon,

wall of window 3 and roll neck 5.

Theybox '6 is adapted to be filled withheavy grease or other .suitable lubricant A for greasing or lubricating the roll necks. In order to feed orfforce the other lubricant up against the rol neck, .I provide a concavely curved grease com pressing and feedin plate 12 which has its lower edge hinge ly secured to the bottom wall 7 of the box 6 adjacent its forf ward free edge by hinge members 14. The

curvature of the plate 12 corresponds to -of the The thickness of the lubricant filled in the box on top of the.

plate.

In order to facilitate the filling of the box 6 with lubricant, one end wall is provided with a projecting filling spout l5.

A cam shaft '16 isjournaled in the box 6 to the rear ofthe plate 12 and carries cams 17 adapted to engage against the rear face plate 12.

The shaft 16 projects through the end I walls 8 ofthe box 6 and a counterweight lever 18 is mounted on one "end of the shaft and projects-rearwardly along one side of the roll housing .2 and is provided with a seriesfof openings 19 for the reception of counterweight 20. v

The force of the counterweight on the lever 18 tends to notate the shaft 16 and therefore rovides a constant pressure of the cams 1 against the plate 12. This constant -pressure against the plate 12 serves to force the lubricant under a constant pressure against the roll necks 5 thus automatically lubricatin the roll necks.

` The use o`f the lu ricating device of this invention for lubricating the necks of roll- 1n friction on the mill, thus decreasing the amount of power required, and also effecting a saving in rolls and roll bearings due to decrease in wear. Also, due to the closeit wil be understood that I do not wish to mill rolls tends to materially reduce be limited thereto, since various modificap ,tions may be made without departing from the scope of my invention as defined in the appended claims.

I claim:

1. An automatic reasing element for the necks of rolling :ni rolls, comprising a lubricant receiving box adapted to be mounted in fixed relation to the roll neck and to contain a quantity of grease, a curved grease compressing and feeding plate hingedly secured along its lower edge to said box, said plate having substantially the same curvature as the periphery of the roll neck, and a counterweighted means for forcing said plate and the grease toward the roll neck, so as to force said grease under pressure against said roll neck.

2. An automatic greasing element for the necks of rolling mill rolls, comprising a lu-v bricant receiving box adapted to be mounted in fixed relation to the roll neckand to contain a quantity of grease, a curved grease compressing and feeding plate hingedly secured along its lower edge to said box, said plate having substantially the same curvature as the periphery of the roll neck, and means for forcing said plate and the grease toward the roll neck, so as to force said grease under pnessure against said roll neck.

3. rlhe combination with a roll housing and roll of a rolling mill, of a grease box mounted in the window of the roll housing for greasing the neck of the rolls, said box being composed of a rear side, end and bottom walls and being positioned with its open side toward the roll neck, said box being adapted to contain a quantity of grease, a curved grease compressing and feeding plate mounted in, and hingedly secured along its lower edge to said box, and means for forcing sai-d plate and the grease toward the roll neck so as to force said grease under pressure against said roll neck.

4. The combination with a roll housing and roll of a rolling mill, of a grease box mounted in the window of the roll housing for greas'ing the neck of the roll, said box being composed of a rear side, end and bottom walls and being positioned with its open side toward the roll neck, said box being adapted to contain a quantity of grease, a curved grease compressing and feeding plate having its lower edge hingedly connected to the bottom wall of said box along its open side, and a counterweighted means for forcing said plate and the grease toward the roll neck.

5. The combination with a roll housing and roll of a rolling mill, of a grease box mounted in the window of the roll housing yfor greasing the neck of the roll, said lbox being composed of a rear side, end andv bottom walls and being positioned with its open side toward the roll neck, said box being adapted yto contain a quantity of grease, a curved grease compressing and feeding plate having its lower edge hingedly connected to the bottom wall of said box along its open side, a shaft journaled in said box, a cam on said shaft, and means for operating said shaftv to force said cam against said plate so as to move said plate forwardly toward the roll neck and thereby force the grease into contact with the roll neck.

In testimony whereof, I have hereunto setY
